Could you please explain the answers in detail? Also, please mention different examples for the same concepts if possible. (Please make the handwriting as clear as possible). Thanks

3. An electron travels with speed 1.7 x 10' m/s between two parallel charged plates as shown. + + + + ++++++ The plates are separated by 1.0 cm and are 1.0 cm charged with a 200 V power supply. a. What is the electric field strength in the space between the plates? b. What is the magnitude and direction of the force on the electron due to the electric field between the plates? c. What is the magnitude and direction of the magnetic field which should be applied to cancel out the electric force on the moving electron?4. Consider an infinitely long current carrying wire which has a radius of R and a current directed out of the page, as shown. a. Draw an Amperian loop with radius r
